topical composition therapy (2013-mcn-333) for the treatment of melasma

Conditions: Melasma

Summary: the purpose of this research study is to gather information on the effectiveness and tolerability of a novel composition of existing u.s. food and drug administration (fda) approved topical medications for the treatment of moderate to severe melasma.

subjects with moderate to severe melasma will apply 0.5 grams (pea-sized) amount of illuminate cream topically to affected areas for 20 weeks. the change in melasma area and severity index (masi) score will be evaluated a baseline and weeks 4, 12, and 20. the masi score is a validated test, calculated by subjective assessment of 3 factors: area (a) of involvement, darkness (d), and homogeneity (h), with the forehead, right malar region, left malar region, and chin, corresponding to 30%, 30%, 30% and 10% of the total face, respectively. the area of involvement in each of these 4 areas is given a numeric value of 0 to 6 (0 = no involvement; 1 = \<10%; 2 = 10%-29%; 3 = 30-49%; 4 = 50-69%; 5 = 70-89%; and 6 = 90-100%). darkness and homogeneity are rated on a scale from 0 to 4 (0 = absent; 1 = slight; 2 = mild; 3 = marked; and 4 = maximum). the score is calculated by adding the sum of the severity ratings for darkness and homogeneity, multiplied by the value of the area of involvement, for each of the 4 facial areas.
